This show is not to be taken seriously. The softest adaptation I have ever watched. Watch it with an open and fresh mind. Where it is like looking at a scrapbook of their love blooming over the years.

I have watched the original Chinese version of this drama four to five years ago. And for sure, this is toned down in a lot of ways. Too many scenes not putted into to this version for it is shorter, and made for Korean viewers. And at times, it felt like a lot is missing, as well as confusing. Not too much unnecessary drama, and the characters actually seemed more close compared to the original. Everyone was just happy with no sort of problems in the world, no conflict, sugar-coated if you might add, and not many may like this sort of drama, but I do. Although the casting choice when it comes to the main couple seems off, I did used to think it would not work, but they pulled it off with their smiles in my opinion. And I can't stop smiling along with them.

Jiang Chen (chinese version) is more stoic, and may seem a bit arrogant. But he is an awkward snowflake we know and love.
Cha Heon, (korean version) smiles a lot more. He shows it, although he's shy about it. We can see that he's struggling between his choice of words when speaking to Sol-i. His friendship with Jinhwan is adorable, and he found a mutual understanding with Dae Sung.

Xiao Xi (chinese version) is a bit more clingy. And like a child, prioritizes her feelings a bit more than others. But, with her positivity, she can conquer anything. Including his love.
Sol-i (korean version) is a toned down of the original, but her cuteness is bubbling within her smiles. She seemed calm and never gets really angry. She never plants any negative emotions on others.

Others may say that this is the disappointing adaptation, but for me, when you say disappointing, I think of Nodame Cantabile's, Naeil's Cantabile. Because although the cast looks the same as the original, and funny, it's kind of disappointing in a lot of levels. Especially, putting Park Bo Gum as a poor second lead that will eventually break your heart. And there's a reason why the original is successful and has a special episodes and two movies, is because it was light, beautiful, and informative. Not too much unnecessary drama.
Or The Liar and His Lover. Joy was beautiful, and Lee Hyun Woo was stunning. But the female lead's character is in a lot of ways annoying. She may not know it, but she's leading at least two or three guys on. When in the Japanese movie, she's calm, understanding, and loved the main guy wholeheartedly from the way he writes his songs.
That are just two examples. Yet everyone has their own opinion when it comes to what's good and what's bad, so go figure.

I guess I'm just really tired of any unnecessary drama and the female lead thinking she has the upper hand of the relationship when in reality, you should just think about it and/or talk it out. So if you want a toned down, short, fluffy, and light drama, then you can watch this with your hearts desire. It cheered me up, them being cute and all making me feel really single. It's a lovely drama and I think Yo Han did a very good job despite it being his first acting experience.

So if you think this drama is too light, then this is not a show for you. Don't write hate comments just because you didn't like it, it's just not really your cup of tea. Drop this cup, despite it being short, don't waste your time. and watch a really complicated drama where all of the main leads suffer. No hate, just love.
